DGCA AME CAR-66 Module 10 Aviation Legislation Exam common mistakes
DGCA AME CAR-66 Module 10 Aviation Legislation Exam · Understand the traps and how to avoid them.
Treating CAR-66 as the document that governs the maintenance organisation's procedures, rather than as the licensing standard for certifying staff.
The CAR-66/CAR-145/CAR-M family share terminology and cross-reference each other, so candidates conflate the licence-holder requirements with organisation approval requirements.
What to do instead
Build a one-page map: CAR-66 = eligibility, categories, privileges and limitations of the licence; CAR-145 = organisation approval and its procedures; CAR-M = continuing airworthiness management. For each practice question, first ask 'who is the subject - the person or the organisation?' before answering.
Assuming a licence category automatically authorises certification of any task on any aircraft type the holder has seen before.
Candidates study the category list in isolation and skip the privilege/limitation text and the type-rating and authorisation concepts that sit around it.
What to do instead
Learn privileges as conditional statements: category + aircraft type/group + scope of work + any organisation authorisation. Practise by writing out, for a given scenario, which of these four conditions fails.
Confusing the Certificate of Airworthiness, the Airworthiness Review Certificate and the maintenance release, and answering questions about validity periods and issuing authority using the wrong document.
All three relate to an aircraft being 'legal to fly', and candidates memorise them as a cluster of facts without attaching each to its issuing body and purpose.
What to do instead
Make a three-column table: document, purpose, who issues it, validity/renewal basis. Answer every question by naming which document the stem is actually about before recalling numbers.
Mixing up the roles of the operator, the CAMO/continuing airworthiness management organisation and the Part-145 maintenance organisation when a question asks who is responsible for a given continuing airworthiness task.
Responsibility is split across several entities by design, and candidates learn each organisation's duties separately rather than as a division of labour.
What to do instead
For each common task (defect control, AD compliance, maintenance programme development, mass and balance, records retention) write down which entity owns it and which entity may perform it under contract. Revise by covering the answer column and reconstructing it.
Answering maintenance programme questions by quoting intervals from memory instead of applying the logic of who approves the programme and what it must be based on.
Candidates over-memorise numbers and under-learn the approval chain (operator proposal, competent authority approval, and the role of the type certificate holder's recommendations).
What to do instead
Learn the chain rather than the numbers: source of recommendations, who develops, who approves, how changes and variations are handled. Treat any specific interval as a distractor unless the stem supplies it.
Muddling ICAO annex subjects and the difference between ICAO Standards and Recommended Practices, and between ICAO obligations and national regulation.
International law is studied as a list of annex numbers with no structure, so items get swapped under exam pressure.
What to do instead
Anchor each annex to a one-line subject and remember that ICAO sets standards while the state implements them through its own rules. When a question asks 'which document requires X', decide first whether it is asking about the international framework or the national rule.
Treating human factors and safety management as general awareness and choosing the 'most reasonable-sounding' option rather than the answer tied to a specific regulatory requirement.
These topics feel intuitive, so candidates skip the regulatory text and answer from everyday judgement.
What to do instead
Study human factors and SMS in their regulatory framing: reporting systems, just culture protections, occurrence reporting duties, and the organisation's safety management obligations. For each option, ask 'is this a requirement, a recommendation, or just good practice?'
Ignoring the record-keeping rules - what must be recorded, by whom, in what form, and for how long - and answering from general impression.
Records are perceived as administrative detail and are revised last, yet they appear across multiple domains.
What to do instead
Create a records matrix: certification records, maintenance records, continuing airworthiness records, and operator technical records, each with owner, content and retention. Note that retention rules differ by record type, so never transfer a period from one row to another.
Misreading 'shall' versus 'should' and 'may' in question stems, and choosing an answer that describes acceptable practice rather than a mandatory requirement.
Regulatory language is dense and candidates read for topic recognition rather than for the modal verb that determines the answer.
What to do instead
During practice, underline the modal verb in every stem before reading the options. Where two options both sound correct, eliminate the one that is merely permitted or recommended when the stem asks what is required.
Confusing CAR-21 (design, production and certification) with CAR-147 (training organisations) and CAR-145 (maintenance organisations), and attributing an approval or privilege to the wrong part.
The numbered parts are learned as a list of titles without the boundary between them, and exam questions deliberately place similar-sounding activities in the options.
What to do instead
Write a one-line scope statement for each part plus the type of approval it grants and to whom. Before answering, identify which part could plausibly grant the privilege described, then check whether the stem's entity matches.
